In this study, a low temperature reforming system with power of 12V/150W has been utilized on an internal combustion engine of motor. The low temperature reforming system included a supersonic atomization device, plasma generator, and controlling devices. The engine is an electronic fuel injection motorcycle engine with 4-stroke air-cooled 125cc cylinder. Syngas from the low temperature plasma reformer mixed with unleaded gasoline has been sent into the IC for measurements. The main purpose of present study is to investigate the characteristics and performance of the IC engine. The engine was tested in 4000, 5000, and 6000 rpm with opening 20{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}, 30{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}, 40{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} and 50{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}, respectively. Fuel consumption and output torque of the IC engine are measured, as well as the emission. The reforming system is capable of generating syngas with 12 vol{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} and 34 vol{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} in 10 seconds and 20-25 seconds after ignition hydrogen below 42℃. Results show that the torque increases with using the low temperature reforming system for 14{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}, 17.89{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} and 21.92{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} with respect to rotational speed of 4000, 5000, and 6000 rpm. It is also shown that the output torque is increased with gasoline mixed with syngas, and the fuel consumption decreases as well. In addition, the emission of CO and HC decreases, especially for higher rotational speed. However, NOx and CO2 emission increases due to better combustion in the engine.
